140,6?9, dated July 8, 1873; application filed Be it known that I, WILLIAM D. BRooKs, of the city of Baltimore and State of Maryland, have invented anew and Improved Soldering Apparatus; and I do hereby declare the following to be a full, clear, and exact descript-ion of the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure lis mainly a vertical section. Fig, 2 is a side elevation partly in section and partly broken away. Fig. 3 is asection to show the peculiar construction of the cock inv tluxpipe 5 and Fig. 4 is a plan view ot' the two-part burner, showing its construction.

The invention relates to machines for sol;

can, or between the cap and top. It will iirst be fullydescribed in connection with all that is necessary to a full understanding thereof, and then clearly pointed out in the claims.

In the drawing, A represents a canin which the top is to be soldered, and B, a holder, provided with l'it't-tube I). C (l is a two-part blow-pipe, having` each a half-circle of burners and a semicircular burner-tube7 C, closed at each end. rlheir ends are brought and held in proximity to each other, and in connection with the reservoir l),- by means of the intermediate coupling-pipes c d. .lhe object ot' this construction is to enable larger or smaller eirclesof burners to be quickly applied to the same machine when a change is made in the size ot' can which is to be soldered. E is a long twopart pipe, through which is fed the wire-solder. c is a block or enlargement, slotted to receive the sliding horizontal knife F, and the two adjacent ends e' c' of pipe. This knife is shouldered at f, to limit the extent ot' its movement, and has a long shank, j", and is connected at the end with a lever, G, that vided with a handle, I, and connected with a pawl, L, that slidesa short.distance up and down in a slot of the tube E. The extent of this movement corresponds to the length ot' solder-wire which maybe necessary foreach can` L is a detent-pawl, attached by an arm to a sleeve, M, fixed on tube E, whereby the solderwire is prevented from any back movement which would interfere with the proper and uniform degree of feed. N is a vessel which holds the resin, oil, or other iux, is attached by an arm to the block, and extends down so as to connect, by a neck, n, with a pipe, O, that is bent and thereby brought directly over the seam to be soldered. N is a cock, placed between vesselN and pipe u, and

having therethrough a slotthat forms an obtuse angle of about one hundred and thirt tive degrees. This slot contains just enough tlux for one can and ea'ch feed. By turning this cock one-eighth of a revolution, its passage-way is made to connect with the neck n that opens into vessel, or the one n that opens into discharge-pipe O.` This cock N is counected with the strap K by an intermediate rod, l), which is pivoted to both.

ly this construction ot' parts the same handle I, and the same. single movement in one direction, feeds the resin to the can and advances the solderi11g-\vire, while the reverse motion then ents oft' and drops the solder on the previously-dropped iiux, and moves the cock to take another supply ofthe flux.

(g is a water-jacket, fastened around the pipe E, and whose object is to cool the wire, that lgradually becomes more or less heated after successive cans have been soldered.

The operation is as follows: The cans are brought up on a carriage-truck or oar, so as to be centered bythe cap-holder ll, that first comes down, andso that the seam which is to be soldered shall come directly under the burners and the pipel". The can then is rc- Volved and is 'quickly heated, while the bit of solder that is cut 011' in vtubo E falls through the lower end thereof, and rests with one end on the can, being melted graduallyi as the can revolves.

Having thus described my invention, what I claim as new, and desire to secure by Letters latent, is-

1. A circle et' burners for a soldering apparatus, having the annular feed-pipe made in two parts, O G, closed at cach end, and provided with coupling-pipes c c, whichadapt them to be -fitted speedily on corresponding pipes d d of the reservoir, as described, so that the circle of burners may be readily enlarged or diminished with the increase or decrease in` the size of cans.

2. The tube E, knife F, and feed-pawl L, combined in a. soldering apparatus, to feed successive bits of soldering-wire, in the man- 'ner set forth.

3. The combination, with the lever G, of the shank f1, the slide J, strap K, and the rod P,
